摘要
提供照明和美化城市的夜间灯光造成大量的电力消耗,使用自发光混凝土替代部分夜间亮化工程,将减少电能的消耗,增强节能减排效果,加速实现我国提出的“2060碳中和”目标。根据现有新型建筑自发光材料以及树脂透光混凝土的制备工艺,采用碱式硫酸镁水泥制备了一种新型自发光混凝土,以发光强度和余辉值作为评价指标,在Matlab软件的帮助下探究其最优发光性能。研究结果表明:在水硫比为1∶15,减水剂的含量为0.76%时自发光混凝土的整体发光性能最优;发光材料的掺入量增加与发光强度成正相关,且掺入量在13%为宜;发光棒尺寸的增加也具有正向作用,尺寸范围在9 mm为佳。
Providing lighting and beautifying night lights of the city cause a large amount of electricity consumption.Using self-luminescent concrete to replace some night lighting projects will reduce the consumption of electricity, enhance the effect of energy conservation and emission reduction, and accelerate the realization of China’s 2060 carbon neutrality target.According to the existing new building luminescent materials and translucent resin concrete preparation process, this article prepares a new type of self-luminescent concrete by using basic magnesium sulfate cement.Using luminescent intensity and afterglow value as evaluation indexes, the optimal luminescence property was explored with the help of Matlab software.The study shows the luminescence properties of self-luminescence concrete reach the best when the ratio of water-sulfur is 1∶15 and the content of water reducer is 0.76%.The increase in the doping amount of luminescent materials is positively correlated with the luminescent intensity, and the doping amount of 13 % is appropriate.The increase of the size of the luminescent rod also has a positive effect, and the size range is better in 9 mm.
